异丁烯水合叔丁醇
摘要:异丁烯作为一种重要的化工原料,主要用作聚异丁烯单体,丁基橡胶,叔丁基苯酚,合成农药等的原料,尤其大量用于制甲基叔丁醚、甲基丙烯酸及酯类。炼油厂的混合碳四,橡胶厂的抽余碳四(SBB)中均含有大量的正丁烯和异丁烯,℃,用常规蒸馏方法难以将其分离,经常直接用作燃料烧掉,成了一定的浪费。本次设计将分离碳四中的异丁烯及其他组分,然后以离子交换树脂为催化剂,将抽余碳四烃中的异丁烯与水化合成叔丁醇,是一种较好的利用碳四烃的方法。

Abstract: isobutylene as an important chemical raw material monomer used primarily as polyisobutylene, butyl rubber, tert-butyl phenol, synthetic pesticides and other raw materials, in particular, a large number for the system methyl tert-butyl ether, methyl acrylic acid and estersclasses. Refinery mixed C4, the Rubber Factory raffinate carbon (SBB) contain a large number of n-butene and isobutene, standing directly due to the boiling point of the two shy of ℃, difficult to separate by conventional distillation methods burned as fuel, has e a waste. This design is the separation of isobutene and carbon four ponents, and then with ion-exchange resin as a catalyst, and will be pumping I C4 hydrocarbon of isobutene and hydration Synthesis of tert-butanol, is a better use of the C4 hydrocarbon method.
Keyword: carbon of isobutylene tert-butanol hydrated

1 概述
馏分是乙烯装置和催化裂解装置的副产物,近年来我国的乙烯工业和催化裂化工业快速发展,。催化裂化装置规模达7000MT,。目前我国抽余烃大部分作为燃料烧掉,因此,抽余烃的中和利用成为石化企业关注的问题。在炼厂的中,异丁烯性质最为活跃且具有化工利用价值,
